blackEffect of Wireframe Lines.
From Tab. REF , the wireframe line works compatibly with CATS and gradients, and prominently improve FID and LPIPS for both image inpainting at \(256\times 256\)  and \(512\times 512\)  resolution. Such phenomenon indicates that lines can provide simple but strong structural priors to overcome artifacts during the generation as in Fig. REF (b), especially for large masking regions and HR inpainting. Moreover, lines enjoy great advantages for man-made scenes as studied in [1]}.
In practice, by using the same TSR, lines can be jointly trained and inference with CATS at negligible additional cost.
